64K CO-DIR MODULE G.703 Co-directional DCM's. Two interfaces provided without signalling, one interface with ABCD signalling (software selectable). Either interface can provide system sync.

AMPCHAMP M-F 4M CABLE 180 DEG Straight through male to female ampchamp cable with 180 deg. headshell.

DUAL BNC-RJ45 ADPT An adaptor which physically converts dual BNC to RJ45. Conversion is physical only, no impedance adaptation. The BNC connections are male, the RJ45 connection is female.

E1-120 OHM LIM MODULE Variant of the E1 LIM (90-0568-01) which only supports 120 ohm interface. All other features of the E1 LIM are supported.

FXO (LGE) MODULE (A-LAW) Single FXO (LGE) module for general applications interfacing to European and International voice terminal equipment with TLP's for receive and transmit of 0 to -7 DB.

FXS (LGS) MODULE (+4/-10DB) clei Single FXS (LGS) module for termination of North American public network services such as UltraWATS, SDN, Megacom and VPN series offering TLP's of -3 to -10DB for receive and +4 to -3DB for transmit. Module operates as FXS or PLAR circuit. This assembly contains a Telcordia CLEI (Common Language Equipment Identifier) label.

LINE VOLTAGE MODULE One per 3612 or 3630 required, if 48V signaling is required with LGS interfaces, or Vbat feed for E<(><<)>(>&<(><<)>)>M type 2 interfaces.

MRD GEN/GEN 600 OHM MOD Manual Ringdown A-LAW Module with 600 Ohm resistive impedance. Tailored for Gen/Gen use only.

RS232/V.24 MODULE clei Single RS232 module providing for dual RS-232/V.24 interfaces per module. Most common synchronous and asynchronous speeds are supported up to 64KBPS. Both HCM and transparent framing formats are supported. This assembly contains a Telcordia CLEI (Common Language Equipment Identifier) label.

X.21 MODULE Supports both DTE and DCE operation. Supports both HCM and Transparent rate adaption. Two control leads supported: C/I. Supports NX56/64 super-rate operation. ***This module cannot be used as a source for system synchronization.***
